Specification of Letters Patent.

Patented Feb. 8, It 916.

Application filed August 13, 1913. Serial No. 784,540.

My invention relates to ventilators applied to the windows ofbarns orother buildings,

and it consists of the features hereafter described and morespecifically pointed out in tion, on line 4-4 of Fig. 2.

the top. Fig. 3'is the same,

' against theinturned flanges Z on the free the claims.

In the accompanying drawings forming a part of this specification,Figure 1 is a perspective of a window embodying thefeatures of myinvention, the sash being closed.

Fig. 2 is the same, the sash being opened at the sash being opened atthe top and raised so it will be open at the bottom. Fig. 4 is avertical sec- Fig. 5 is an enlIarged horizontal section on line 55- of*ig. 3.

Referring to the drawings, Figs. 1, 2 and 3 represent a window set in awall, a portion of which is represented by A. B represents the insidehead casing, B the outside head casing, G the inner side casing, C theouterside casing and D the apron of the window frame. E is a single sashhaving nine panes of glass G. F represents the lintel, H the.

side jambs, I the stool, J the sill of the window frame, K the sidewindow stops and K i the head window stop;

A pair of sheet iron shields L, cut wider at the top than at the bottomand having flanges on their op .'osite edges,-the flanges on the edgesnext t e wall being turned outward and the flanges on the other edgesbeing turned inWard,-are secured to the inner side casings C preferablyby screws 6 passed through holes'in the ad acent flanges, as shown, andare further supported by braces b secured at one end to the shield'andat the other to the wall. The sash is set in the frame so as to rest onits outer side against the window stops K and K and is held in place onits inner side by a sash latch M at the top and the stool I at thebottom.

The edge of the stool adjoining the sash is beveled to correspond withthe incline of the flanges Z on the instanding edges of the shields L,and when the latch M is released the sash will be free to tilt inwardand will rest against the-bevel edge of the stool and edges of theshields L, as shown most plainly in Fig. When in this position therewill be a free ingress of the outside air throughthe opening at theupper edge of the sash which will be deflected by the inclined positionof the sash toward the ceiling, thus mixing the cool air in cold Weatherwith the warmer air in the building and avoiding.

drafts upon the animals in'the building.

To hold the sash in this position and prevent it from being dashed backand forth by the wind, I provide two dogs N, (one on each side) andpivot their outer ends to the sides .of the window frame, preferably bymeans of screws S to the stops K, so. that they will'be free todropngainst the side rails of the sash and hold it in position. The endsof the dogs whichrest upon the sash are preferably bent upwardly at anangle to fit the incline of the sash when resting on the flanges of theshields, as shown in Fig. 4.

The dogs are made long enough so they will not drop down past theportion of the sash nearestthe screws S, but will rest on the sash justabove this point. The sash may be slid up the incline of the flanges Zthey will prevent its downward movement and will hold it inelevatedposition at any point within the scope of the contact of thedogs with the sash as shown in Fig. 3.

To lower the sash it must first be slightly raised and, at the sametime, pushed away from the flanges of the shields against the dogs andtoward the stops K. This move ment of the sash will raise the free endsof the dogs and will cause them to assume the position shown by dottedlines in Fig. 4. When the dogs are in this position the sash 1 will befree to drop to its closed position as the screws S, as shown in Figs.2, 3 and 4.

whereby the dogs will be 1101 a so they will be free to drop against theside rails of the saslr as soon as it is tilted against the flanges ofthe shields.

It is preferable that the shields be extended down only far enough toclose the open ings between the inner side facings (C and the sash whenit is tilted in against the flanges on the free edges of the shields L,as shown in the drawings. This is all that 1s without any interferencefrom the dogs, but

necessary and in this way the inward and outward flanges of the shieldsat the lower ends may be kept the'thickness of the sash apart instead ofbeing continued down until they run into each other or occupy the sameplane, which, while not being needed, would make the shields hardertomake The latch M is adapted to engage a catch T on the edge of thelintel F from which it. is re leased by a pull on a cord U. The sash maybe removed from the Window or replaced without having to remove orreplace any of the parts. a

By beveling the edge of the stool next the sash to correspond with theincline of the free edges of the shields L, the sash may be tiltedagainst the flanges Z without binding or being cramped between the stoolI and thelowerends of the stops K. Also, when closed, any water that mayhappen to be on the inside of the sash-by the melting of frost on theinsides of the window panes or otherwise will run more freely out underthe sash by reason of the opening between the sash rail and the upperedge of the stool than if it was fitted closely against the sash,

rail at its upper edge in the usual manner.

The entire arrangement is simple and inexpensive and is thoroughlyeffective in operation.

What I claim is:

1. In window construction a sash fitted' 'in a frame so its upper endwill tilt in-' wardly, a pair of shields out wider at the top than atthe bottom and having inwardly turned flanges on their free edges, theineline of the flanges corresponding approximately with the incline ofthe sash when tilted in, and the sash being adapted to be slid up theflanges, and a pair of dogs pivoted at their outer ends to the sides ofthe window frame and their inner ends adapted to come in contact withtheside rails of the sash and prevent it from tilting out as well as tohold it in raised position when slid up the flanges.

2. In window construction a sash fitted in a frame so its upper end willtilt inwardly, a pair of shields out wider at the v top than at thebottom and having inwardly turned flanges on their free edges to receiveand hold the sash when tilted in, dogs pivoted to the sides of thewindow frame to hold the sash in this position, said dogs being adaptedto stand in an approximately vertical position when the sash is tiltedinto closed position, and means to prevent the dogs from tilting overaway from the sash.

3. In window construction a sash fitted in a frame so its upper end'will tilt inwardly, a pair of shields cut wider at the top than at thebottom and having inwardly turned flanges on their free edges to receiveand hold the sash when tilted in, and a stool on the bottom of thewindow frame adjoining the inner face of the lower sash rail, beveled onits adjacent edge to fit the incline of the sash rail when tilted in,and thus insure a close fit between the edge of the sash rail and thestool whether the sash is tilted 70 in or tilted out.
